I took this picture with a Nikon D750 using a Nikon 24-120mm f/4.0 lens @ 31mm, a Pro Optic sky filter and a Pro Optic CPL. Is the vignetting caused by:

1. A CPL on a sky filter?
2. The CPL came as part of an "accessories" package so it may not be of the highest quality?
3. Panned to 31mm with a 2-filter stack?

Thanks,

Dennis

Yes, the CPL is probably too "deep" for the wide angle of the lens. Pretty easy to crop and remove, and it would not detract from your image if you did so.

Filters and wide angle will often result in vignetting. Just crop as mentioned above.

In my experience when you have really dark corners it is usually a filter or lens hood. One would expect it to be even more pronounced at 24mm.

As others point out, it's the two filter stack.

You could zoom out to 35mm instead of 31, or, remove the Skylight filter. You don't really need a Skylight or UV filter on the front of your lens. The coated glass on the end repels water, dirt, and fingerprints. The filter doesn't.

Check your lens hood if you used one.

Good Morning Dennis
Try filling in the vignette Blue Sky using Lightroom or Photoshop.

Stacking filters is seldom a good idea. I believe you have hit upon one of the consequences.

Thanks everyone. For the record I did crop it to remove the vignetting. I just wanted to know what caused it.

Why 2 filters ?

Dennis, I would say that it is using the two filters at the same time, as you noted, "a Pro Optic sky filter and a Pro Optic CPL". My suggestion would be to remove the sky filter anytime you are using the CPL. I've run into this issue when using a 25A and CPL together. I know it's going to happen. So, I plan around that.

Hey Dennis
How about sharing the final cropped photo?

Over filtered. You don't need either filter. Once I went totally digital, I stopped carrying filters except for a Kodak gel ir filter. That filter gets used about every six months.

This is a very important point. LR has a built-in polarizer. Works like a charm if you do not blow out the highlights in the sky. The main purpose now for a polarizer is to eliminate reflections on glass and glossy surfaces.

Also, depending upon your orientation to the sun and scene, the polarization will vary from one edge to another. You have to be very careful and, if possible, shoot with and without the polarizer.

In this post, I would probably just crop the darkening in the top corners. It is not that back down below. If you do not want to, get rid of them with a simple tool like the healing tool.
